OK I read it....it is a really big rain event...hypothetical.

ARkStorm

From Wikipedia, the free encyclopedia

An ARkStorm (for Atmospheric River 1000 Storm) is a hypothetical but scientifically realistic "megastorm" scenario developed and published by the United States Geological Survey, Multi Hazards Demonstration Project (MHDP). It describes an extreme storm that might impact much of California causing up to $725 billion in losses (most caused by flooding), and affect a quarter of California's homes. The event would be similar to exceptionally intense California storms which occurred between December 1861 and January 1862.[1] The name "ARkStorm" means "Atmospheric River (AR) 1000 (k)."

I would say “hypothetical” only in the details. We know these are common events, viewed on any kind of time scale at all.

We know how to mitigate at least some of this, but (with kudo’s to Babylon 5 for most if not all of the original thought), instead we have a case of:

Analyze problem.
Develop solution.
Do the opposite.
